K3(K₁+K₂)/2

K3 = K₁.K₂

K3 = (K₁.K₂)2

K3 = (K₁.K₂)0.5

Liquid phase reactions

Large scale gaseous phase reactions

There is no change in number of moles in gaseous reaction

All of these

The feed rate is measured at temperature and pressure in the reactor

The temperature, pressure and the density of reaction mixture remains constant throughout the reactor
